a professional labeling instrument, not a throwaway plastic pen
Each MagicTag marker is built to perform where ordinary markers fail. Cheap plastic alternatives are made from soft, brittle materials that crack, with tips that dry out and stop writing, and inks that wash away with water, solvents, or even light handling. Their so-called “alcohol resistance” applies only to diluted, watered-down alcohol.
MagicTag’s proprietary inks undergo weeks of high-energy mixing to stabilize nanostructured carbon black and red pigments, ensuring decades of clog-free use. Each marker is engineered with a precision aluminum barrel, a stainless-steel mixing ball, and Bakelite components that will not deform or crack under chemical or thermal stress. The porous fiber nib meters ink with controlled precision, producing sharp, permanent lines on paper, glass, metal, and even wet surfaces. The oil-based inks resist full submersion in full-strength, undiluted solvents.
MagicTag is a professional labeling instrument — not a throwaway plastic pen.
built for a task
Writing instruments are made for specific tasks.
Magic Tag Engineering Markers are permanent markers built for critical labeling where reliability is non-negotiable.
Built to outperform standard markers, Magic Tag markers produce bold, fade-resistant marks that stay vivid in tough conditions. They are trusted by professionals in labs, manufacturing, aerospace, healthcare, and creative fields.
a specialized permanent labeling marker
The markers are made with carbon black and pigment-based inks. This means the inks withstand immersion in ethanol, isopropanol, acids, alkalis, bleach, peroxide, UV light, extreme heat, and cold.
The markers perform reliably on moist or wet surfaces, making them ideal for autoclaves, freezers, and production lines where condensation causes ordinary inks to fail.
outstanding design
Each set includes three markers: one broad-tip red marker for bold, high-visibility labeling, and two fine-tip black markers for precision work.
Features include:
-
An aluminum barrel for lasting durability
-
A stainless-steel mixing ball for consistent ink flow
-
1 mm and 4 mm fiber tips for smooth labeling with minimal bleed-through on paper
dependable performance
Magic Tag markers write every time — never drying out before the ink is fully used. The markers remain ready to write instantly, after years in storage. No more reaching for dried-out markers that fail during critical labeling applications.
With simple maintenance — an occasional wipe of the cap with a cloth — Magic Tag markers continue to deliver crisp, high-contrast black and red labels in high-stakes environments where durability and permanence matter.

technical data
packaging & availability
The Magic Tag Engineering Markers are supplied in a box containing three markers: two fine-tipped markers in Perma Black and one medium-tipped marker in Scarlet Red.
physical description
MagicTag Engineering’s PermaBlack marker is a 1 mm fine-tipped porous-tip instrument, while the Scarlet Red marker is a medium-tipped red marker. Both are engineered for durable, high-contrast labeling in demanding technical environments, including laboratories, industrial facilities, and specialized applications.
Each marker incorporates a porous polymer nanostructured nib, bakelite polymer components, and a durable aluminum barrel housing a stainless-steel mixing ball and a 5 mL ink reservoir. The inks are oil-based, formulated with carbon black (PermaBlack) or red pigments (Scarlet Red), blended with plant oils and alcohol-based solvents, and maintained at pH 6.5–7. They are designed for reliable performance under extreme conditions, resisting ethanol, isopropanol, acids, alkalis, bleach, peroxide, UV light, heat (up to 200 °C), and cold (down to –200 °C).
The porous nib meters ink through capillary action, producing solid, uniform strokes with consistent line density, slight edge feathering, blunt initial and terminal strokes, and heavier deposition under pressure. The stainless-steel mixing ball maintains ink homogeneity after storage, re-equilibrates the dispersion network, and restores smooth capillary flow.
cleaning and maintenance
To ensure optimal performance:
-
Regularly wipe the cap and barrel collar with a clean rag to maintain a proper seal.
-
If the cap is difficult to open or close, clean the barrel to remove any residue.
-
Routine cleaning prevents ink buildup and extends marker life.
The ink is oil-based and can be cleaned with turpentine, hexenes, hexane, aliphatic hydrocarbons, or oils.

solutions for oils
Tape: For surfaces exposed to oils, placing clear tape over the label will significantly extend its lifespan.
For maximum durability, use a Low-Density Polyethylene (LDPE) Film Tape, sometimes called Greenhouse Repair Tape. LDPE tapes are usually opaque, but they are highly resistant to hydrophobic solvents and protect labels effectively.
For most everyday uses, standard packaging tapes such as clear BOPP or PET-based tapes offer sufficient protection.
disposal instructions
Once the marker is spent, any remaining ink is immobilized in the fiber tip and chamber materials, making it safe for disposal in solid waste streams.
-
Used or empty markers can be disposed of with normal trash.
-
Each marker contains only about 5 mL of ink, fully contained within the chamber. Do not attempt to disassemble the marker or access the ink reservoir.
if a marker leaks
If the marker becomes disassembled and leaks ink:
-
Blot the leak with a paper towel or cloth. Allow the towel/cloth to dry fully, then discard it with household trash.
-
Clean affected surfaces with soap and water or a compatible solvent such as ethanol or isopropanol.
-
Wash your hands after cleanup with a hydrophobic cleaner or soap.
